A 43 year-old female, who underwent bilateral lung transplantation for Eisenmenger syndrome 10 years previously, visited our hospital complaining of progressive severe dyspnea. She was diagnosed as having. bronchiolitis obliterans syndrome, which was presumably caused by chronic graft rejection following lung transplantation. Due to the aggravated dyspnea despite medical treatment, she required ventilator care and then she underwent lung retransplantation. We report here on a case of lung retransplantation for treating chronic graft rejection following the previous lung transplantation for the first time in Korea.

Nonocclusive mesenteric ischemia (NOMI) is a rare complication that occurs in about 0.05% of patients after openheart surgery, and NOMI refers to the mesenteric ischemia that's caused by splanchnic vasospasm without occlusion of the great intestinal vessels. In the presently reported case, NOMI developed to maintain the blood flow to the heart and brain after several minutes of a hypotensive status and the latter was caused by acute aortic dissection that complicated an aortic cannulation procedure. Unfortunately, the patient died even though the problems were diagnosed early and proper treatment was administered. Early diagnosis of NOMI by angiography and the selective infusion of vasodilators are thought to be the only way to improve survival for patients with clinically suspected NOMI.

Glomus tumor is a distinctive type of perivascular tumor whose cell type is a modified smooth cell that closely resembles the glomus body, and this is where the tumor's name is derived. This kind of neoplasm is a benign and rather uncommon neoplasm that can be found in any part of the body, yet it is most commonly seen in the subungual area. Glomus tumor of the trachea is extremely rare. We present the clinicopathologic findings of a resected glomus tumor of the trachea along with a review of the related literature.

A 67 years old male patient was admitted with back pain that had recurred from 6 months previously. Eleven years previously, he underwent stent grafting at the descending thoracic aorta for a chronic Stanford type B aortic dissection. The preoperative computed tomography showed aortic dissection from the origin of the left subclavian artery to the bifurcation of the abdominal aorta, and there was a type I endoleak at the proximal portion of the stent graft and aneurysmal dilatation of the descending aorta. A hybrid endovascular repair was successfully performed, and this involved debranching and rerouting the aortic arch vessels under extracorporeal cardiopulmonary bypass and then this was followed 13 days later by stenting in the ascending aorta, the aortic arch and the descending aorta. The postoperative computed tomography showed complete exclusion of the type I endoleak. After discharge, he has been followed up for 8 months without any problems.

Background: Cervical tuberculous lymphadenitis is the most common form of peripheral tuberculous lymphadenitis. The American Thoracic Society recommends 6 months of isoniazid, ritampin, ethambutol and pyrazinamide for treatment of peripheral tuberculous lymphadenifls, but even with this recommended treatment, frequent relapse occurs in actual clinical situations. Material and Method: The medical records of 38 patients diagnosed and treated for cervical tuberculous lymphadenitis between February 1997 and February 2007 were retrospectively reviewed. Result: The study included 14 males (36.8%) and 24 females (63.2%), with a mean age of $36.9{\pm}16.3$ years. The most frequent symptom was palpable neck mass in 24 patients (63.2%); 10 patients (26.3%) complained of fever or chills. Only nine patients (23.7%) had radiologic abnormalities. All patients received anti-tuberculous medications for at least 7 months, with isoniazid, rifampin, ethambutol and pyrazinamide for the first 2 months, and then isoniazid, rifampin and ethambutol given for more than 5 months. Relapse occurred in 7 patients (21.2%). Conclusion: Since many patients with cervical tuberculous lymphadenitis have no symptoms and show no radiologic abnormalities, diagnosis and treatment tend to be delayed. Considering the high relapse rate, the anti-tuberculous medication period should be longer than 6 months and this is recommended by the American Thoracic Society.

Background: A hybrid procedure using an open surgical extra-anatomic bypass of aortic arch vessels and thoracic endovascular aortic repair (TEVAR) is less invasive than open surgery, and provides a suitable proximal landing zone. Here we report our experience with a hybrid TEVAR procedure at a single center. Material and Method: We retrospectively reviewed consecutive patients with thoracic aortic disease who received a hybrid TEVAR procedure between August 2008 and January 2010. Patients' data were prospectively collected and mean follow-up was $10.8{\pm}5.5$ months (range 3~20). Result: Nine patients (7 males and 2 females) with a mean age of $63.8{\pm}15.8$ years (range 38~84) underwent a hybrid procedure. Five patients had an arch or a proximal descending aortic aneurysm, two had a dissecting aneurysm of the descending aorta, and two had an aneurysm of the ascending arch and descending aorta. Mean expected mortality calculated by logistic EuroSCORE was 21%. Six patients underwent debranching and rerouting from ascending aorta to arch vessels, 2 had carotid-carotid bypass grafting, and 1 underwent carotid-axillary bypass grafting. Mean operation time was $221.4{\pm}84.0$ min (range 94~364). Deployment success of endovascular stent grafting was 100% with no endoleak on completion angiography. There was no mortality, and a small embolism in the branch of the right opthalmic artery in one patient. During follow-up, one intervention was required for the endoleak. Actuarial survival at 20 months was 100%. Conclusion: Early and mid-term results are encouraging and suggest that hybrid TEVAR procedures are less invasive and safer and represent an effective technique for treating thoracic aortic disease.
